Definitions

  • the invention relates to a control unit for control functions within a Vehicle cabin according to the preamble of patent claim 1.
  • control panels are such.
  • Previously common latching devices (DE 295 01 692 U1) have latching elements such as resilient balls, leaf springs, etc., which put a considerable load on the Storage etc. cause, in addition to locking also a tightness of the Knob.
  • the invention is therefore based on the object of measures find with whom a sensitive locking of a generic Knob can be reached without increasing the actuating force.
  • Fig. 1 shows a view of an opened operating unit housing 1 in which a is supported by a plurality of not-illustrated rotary knobs 2, the position of which is indicated by an illuminated display, which consists of a LED (maybe L E mittierendes D evice) and a fixed with the knob 2 connected light guide body 4 is formed.
  • an illuminated display which consists of a LED (maybe L E mittierendes D evice) and a fixed with the knob 2 connected light guide body 4 is formed.
  • FIG. 2 a cross section of the control unit housing 1 is shown in FIG is that goes through the knob 2, the light guide 4 acts directly with the LED 3 together and has a light exit surface 5, which with a Light entry surface 6 of a light guide plate 7 cooperates with the other Knobs leads.
  • the light guide body 4 connected to the rotary knob 2 on axial surfaces 8, 9 of an outer edge 10 each have locking knobs and depressions 11, 12 which cooperate with latching hooks 13 of a clamp spring 14 which are pushed onto the light guide plate 7 within holding ribs 15 and locked in the push-on direction between a light guide plate edge 16 and a housing rib 17.
  • FIG. 1 it can be seen from FIG. 1 that the latching knobs and recesses 11, 12 are arranged on the axial surface 8 in close succession for a sensitive Locking in intermediate positions and that on the other axial surface 9 only Locking knobs and a recess 11, 12 each for a locking in the end positions of the rotary knob 2 are provided, as shown in FIG. 3, in the a cross section of the control unit housing is shown, which in the direction of Clip spring is placed.
  • the clamp spring 14 has a first pair of clamps 20 for interacting with the latching knobs and recesses 11, 12 and a second pair of clamp arms 21 for clamping on the light guide plate 7. These pairs of clamp arms 20, 21 bring about a force equalization of the opposing support forces, so that there is no load on the bearings.
